For over 100 years, the middle 1700’s to the mid 1800’s, motors powered by electricity were nothing more than a curious novelty or a great study matter. In short, electric motors and especially electrostatic motors were comparable to Hero’s steam engine.
Scotsman, Monk, scientist and inventor Andrew Gordon can be credited with developing the first electrostatic motor, much like in the video. Ben Franklin had an interpretation of this as did many other tinkerers of the day. These motors work due to attraction and repulsion of opposite charges, much like a magnetic motor which came after, but with high voltage Direct Current as opposed ti magnets and electromagnets.
Thanks to Faraday and that cohort, electricity became less of a mystery and was finally harnessed in the form if low voltage Direct Current to preform rotational work on a practical level in the late 1830’s. Tesla invented his Alternating Current Induction Motor in 1887 and revolutionized pretty much everything in terms of being practical due to the fact that it runs from wall current.
Electrostatic motor are just starting to be thought of as practical work horses, thanks to advances in electronics and power supplies to provide high voltage for long periods of time.
